IMPROVEMENT IN REELS FOR COILING METAL STR|P'S.

Specification forming part of Letters Patent No. 222,14 8, datedDecember 2, 1879; application filed- May 1, 1879.

To all whom it may concern:

Be it known that we, WM. W. MINER and V BENJ. BEVELANDER, both ofBoston, county of Suffolk, State of Massachusetts, have invented'anImprovement in Reels for Winding or Coiling Metal Strips, of which thefollowing description, inconnection with the accompanyin g drawings, isa specification.

This invention relates to a reel or mechanism by which it is possible towind metal, as nail-plate and hoop-iron, leather, or other belting, 8m;and the invention consists, chiefly, in a reel provided with clampingmechanism, actuated as herein after described, to automatically graspthe end of the material to be wound, and to release it at the propertime, so as to permit the material to be removed from the reel.

Figure 1 represents, in front elevation, a reel embodying our invention,the clamping portion thereof being opened; Fig. 2, a similar view, theclamping portion being closed; and Fig. 3 is a side elevation.

The main disk at of the reel is mounted loosely upon shaft 11, near itsend, the shaft being held in a suitable hearing, as at c. The shaft bhasattached to it, by a key or spline, 2, a clutch part, d, madelongitudinally movable along the shaft by an elbow-lever, c, pivoted at3, and connected by a link, f, with a foot-treadle, g, lifted by aspring, h.

The clutch part d has one or more lugs, 4, which, when the said part dis in the position shown in Fig. 3, engages with a projection,.5, on thedriven pulley 43, mounted loosely upon shaft b, and causes the saidpulley, with its lugs 5, forming one-half the clutch, to engage theother half, (Z, and rotate the shaft 1).

The disk has one or more fixed receivingflanges,jj, and one or moremovable clampingflanges, k 76, (in this instance made as segments,)about'and upon which the strip of metal or nail-plate is to be wound,the shape of the pieces j 70 and their size governing the shape and areaof the space at the center of the coil of material.

The movable receiving-flanges 7c are, in this instance, shown as carriedby slides l, made movable in guideways m under the action of a cam, a, aspring, 19, holding the end 7' ofthe slide against the cam n. This camis fixed upon the shaft Z), and when the reel composed of the parts aj kis in the position shown in Fig. 1, the movable parts, acted upon by thespring 9, are drawn toward the axis of the shaft b, so as to leavespaces 8 between the ends of j k, in either of which may be entered theend of the thing to be wound into a coil.

The shaft 1), being partially rotated, starts the cam n, the reel beingloose, and the cam forces the flanges k, with slides l, outward, as inFig.2, bringing the ends of j it together, so as to bite the end of thematerial snugly, and then the further rotation of the shaft in and itscam 12 carries with it the reel and winds the material in coil formabout the receiving and clamping flanges j it.

After the proper amount of material has been placed upon the reel, itmay be tied or wired by inserting a wire about the coil through theslots 8.

To remove the coiled material, stop the rotation of shaft 1) bydepressing the treadle, thereby moving cl away from its engagement withpulley t' or lug 5. Then turn the reel backward by hand for part of arevolution, or far enough to permit the spring 10 to draw the flange kinward and release the end of the strip, after which the material may beremoved laterally from the flanges j k.

Referring to the drawings, Fig. 1, it will show that the length of thereceiving-flanges j of the reel, upon which are wound the metal strips,are of less length, or occupy a less portion of the arc of a circle,than do the movable flanges 70 plus the spaces 5. This construction isessential, as it permits the coiled metal strip to be easily removedfrom the narrow flanges j, which occupy but a small part of the are of acircle.

The flanges 70 might be pivoted at one end, and be acted upon betweentheir ends by a suitable cam, so as to throw the said flanges outward tograsp an end of the material to be wound, one flange, It, thuscooperating with the other flange, j, and acting as a clamp for the endof the material.

The friction devicezr holds thereel back when the cam and shaft begin torotate.

The receiving-flanges j are, it will be noticed,

quite narrow, and in practice need be but little, if any, wider than thewidth of the strip of nail-plate'to be wound.

The end of the strip to be wound is so held by the movable flange k thatsuccessive coils or layers of thenail-plate are wound one upon theother, as in an ordinary coil of tape.

WVe claim 1. In a reel for winding a strip of metal plate, one coil orlayer directly and closely upon and outside of another coil or layer,the disk a, having fixed receiving-flanges j, combined with aradially-movable flange, 70, located within the flanges j, and with theshaft 1) and devices, substantially as described, to operate the movableclamping-flange k, to hold the end of the strip of metal plate withinthe circle of the flanges j, as and for the purpose described.

2. The receivingflange j and the radiallymovable flange 70, combinedwith a cam to operate the movable flange, substantially as described.

3. The disk a, proy'ided with the fixed receivin g-flan ges and the clampin g-flan ges, combined with a cam fixed upon the shaft, and located tofirst actuate the clamping-flanges to grasp the end of the material tobe wound, and then to rotate the disk and receiving-flanges,substantially as described.

4:. The dish or, held loosely upon the shaft b, and provided with fixedflan ges j and the movable flanges 7c, and a cam fixed on the shaft toactuate the movable flanges It automatically, combined with the shaft11, the drivingilley, and a clutch to engage the shaft with thedriving-pulley and disengage it therefrom, substantially as described.

5. The fixed receiving-flangej and the movable clamping-flange, and ashaft and cam to actuate it to clamp the end of the strip to be woundinto a coil, layer upon layer, combined with a friction device,substantially as described, to hold the disk stationary until the shaftmoves far enough to actuate the clamping-flange and grasp the strip tobe wound, substantially as described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
